Has anyone used Peter's for HTing 52100? Did they do a good job? I heard that 52100 is a hard steel to HT so I want to make sure to send it to the right person.
 
I've never had them HT 52100 but they've done S35VN, 3V, CPM D2, and A2 for me, all with excellent results.
I think if they can do the super steels 52100 would be a piece of cake.

They are in the business of heat treating steel professionally. When people say it is hard to HT they mean for us as amateurs working with often homemade or bodged together old equipment.

For those of you using peter's for 52100 HT, what is type of numbers are you getting back on your HRC?

*Hopefully this post doesn't add to the zombie post issue.
 
I asked them to shoot for 58Rc for a good balance of toughness and edge-holding, and they nailed it. I'm not sure of the upper hardness limit for 52100, but they probably have good advice on that. Give them a call and ask for Brad if you have detailed questions about your specific application.
 
Peters did my tomahawks and a knife made from 52100. The edge on my hawks is 58 and is holds up well. You can chop through multiple pieces of copper piping with no damage. I had them HT a 52100 knife as well for testing. The edge is at 60 and I think it holds up very well.
 
With low temp (1475) salt bath austenizing and oil quench, folks have been able to get as quenched hardness as high as 67Rc.

That's fascinating, and higher than I would have guessed. Any reports on how far they had to temper it back for their purposes? What about retained austenite?

For the sake of clarity, the 52100 blades I had done by Peters were fairly stout and intended for rough/combat/utility use, hence my request for moderate final hardness and an emphasis on toughness over pure hardness/wear-resistance. I imagine that for a really thin slicer/kitchen knife etc, a notably higher hardness would be indicated.
 
I have a batch of 52100 at Peters right now. I requested 59 rc this round. Brad told me they can typically get you within a half point rc of your required hardness. Give them a shout if you have any questions.

Ive been using peters for a while and I have met brad a few times. if he says he can do it he can, I have never been disappointed with his service.
